For me, prolonged stress is a massive trigger for my OCD as it allows intrusive thoughts to flood in, and the themes of my thoughts often switch. Lots of my intrusive thoughts have centred around identity and self-worth, causing me to ruminate and/or obsessively go through them. I one time just said to myself "I am not my thoughts" which massively helped- OCD is a deceptive and tiresome condition in my opinion. Of course, I also get the checking compulsions and the list goes on and on. I really relate to the procrastination part and it is one thing that has bothered me so much, because its like "I've got no reason to procrastinate, so why am I doing it?" And it is down to the time spent daydreaming/ruminating or doing whatever else I want to do first.
Also, distraction/relaxation is helpful for me, as it calms my nerves and takes the focus away from the thoughts (however, this is only a distraction, not a definitive treatment). I know it sounds cliché, but have you tried arranging appointments GPs/mental health services (I know they take a while) as it may help you get access to ERP (Exposure-Response Prevention) which is supposed to be the "golden-standard" treatment for OCD. I do hope things get better for you, it is most definitely awful and it consumes your day. I won't ask you if you have tried going over your thoughts, as that just feeds into OCD.
If you haven't already, try the OCD-UK website. It's got lots of helpful information on OCD and its treatment.
Hope your OCD gets better.
